Answer:

2Al+1.5O2→Al2O3

Thus, 2 mol of Al combine with 1.5 mol of oxygen to form 1 mol of Al2O3.

2 mol of Al corresponds to 2×27=54 g.

Thus, the weight of Al used in the reaction is 54 g.

The element is Magnesium

It has total 12 electrons

it has electronic configuration

$\\ \sf\longmapsto 2,8,2$

$\\ \sf\longmapsto 1s^22s^22p^63s^2$

In valence cell it has 2 electrons and therefore its valency is 2

Quantitative is anything that is relating to a number value. Think “quantity”

Example:

1. There are 5 ml of water
2. There are 3 beakers
3. It takes 30 minutes for the reaction

Qualitative is about characteristics that can be described

Example

1. The liquid is green
2. The solution turned into a gas
3. Bubbles were produced
